Comprehending the lack of access to maternal and neonatal emergency care: Designing solutions based on a space-time approach.

OBJECTIVE: The objective of this study was to better understand how the lack of emergency child and obstetric care can be related to maternal and neonatal mortality levels. METHODS: We performed spatiotemporal geospatial analyses using data from Brazilian municipalities. An emergency service accessibility index was derived using the two-step floating catchment area (2SFCA) for 951 hospitals. Mortality data from 2000 to 2015 was used to characterize space-time trends. The data was overlapped using a spatial clusters analysis to identify regions with lack of emergency access and high mortality trends. RESULTS: From 2000 to 2015 Brazil the overall neonatal mortality rate varied from 11,42 to 11,71 by 1000 live births. The maternal mortality presented a slightly decrease from 2,98 to 2,88 by 100 thousand inhabitants. For neonatal mortality the Northeast and North regions presented the highest percentage of up trending. For maternal mortality the North region exhibited the higher volume of up trending. The accessibility index obtained highlighted large portions of the rural areas of the country without any coverage of obstetric or neonatal beds. CONCLUSIONS: The analyses highlighted regions with problems of mortality and access to maternal and newborn emergency services. This sequence of steps can be applied to other low and medium income countries as health situation analysis tool. SIGNIFICANCE STATEMENT: Low and middle income countries have greater disparities in access to emergency child and obstetric care. There is a lack of approaches capable to support analysis considering a spatiotemporal perspective for emergency care. Studies using Geographic Information System analysis for maternal and child care, are increasing in frequency. This approach can identify emergency child and obstetric care saturated or deprived regions. The sequence of steps designed here can help researchers, and policy makers to better design strategies aiming to improve emergency child and obstetric care.

[Proposal for a methodology to estimate the potential coverage of primary care teamsPropuesta de una metodología para estimar el área de cobertura potencial de los equipos de atención primaria]. / Proposta de metodologia para estimar a área de cobertura potencial por equipes de atenção primária.

OBJECTIVE: To present a methodology for the empirical evaluation of primary health care (PHC) through the construction of digital representations of potential PHC coverage areas. METHODS: In this methodological study, potential areas were constructed by combinatorial analysis between census tracts and the location of basic health units with working PHC teams in Brazil. Six rules were used to parameterize the algorithm for the construction of potential areas. Thus, six restrictions were applied to enable the model: the selection of census tracts near the basic health unit; contiguous sectors; mutually exclusive sectors; sectors located in the same municipality of basic health units; sum of 4 500 users per health team in each unit; and volume of population ascribed proportional to the number of PHC teams allocated to the unit. Based on 316 594 census tracts and 39 758 basic health units, a neighborhood matrix was developed. To that matrix, a graph algorithm was applied to test combinations of sectors that simultaneously met the stipulated rules. RESULTS: A total of 1 901 114 arcs were defined, connecting 30 351 census tracts, allowing the construction of 26 907 potential areas. Based on these results, intra-municipal analyses can be performed to monitor PHC indicators. Customizable algorithm parameters can be adjusted to accommodate different sets of rules which may be adapted to different countries. CONCLUSIONS: The use of geoprocessing approaches creates conditions for the assessment of PHC impact, based on secondary databases at various levels, such as intra-municipal, basic health unit, and even at the team level.

OBJETIVO: Presentar una metodología para la evaluación empírica de la atención primaria de salud (APS) a través de la construcción de representaciones digitales de las áreas de cobertura potencial de los equipos de APS. MÉTODOS: Estudio de tipo metodológico. Las áreas potenciales se construyeron mediante un análisis combinatorio entre los sectores censales y la localización de las unidades básicas de salud con equipos de APS que trabajan en Brasil. Se utilizaron seis reglas para parametrizar el algoritmo de construcción de las áreas potenciales. Así, se estipularon seis restricciones que viabilizaron el modelo utilizado: selección de sectores censales cercanos a la unidad básica de salud; sectores contiguos; sectores mutuamente excluyentes; sectores ubicados en el mismo municipio de la unidad básica de salud; suma de 4 500 usuarios por equipo de salud en cada unidad básica de salud; y volumen de población adscrita proporcional al número de equipos de APS asignados en la unidad básica de salud. A partir de 316 574 sectores censales y 39 758 unidades básicas de salud se desarrolló una matriz de vecindad sobre la cual se aplicó un algoritmo gráfico que evaluaba las combinaciones de sectores que cumplían simultáneamente las reglas estipuladas. RESULTADOS: Se definieron en total 1 901 114 arcos, que conectaron 30 351 sectores censales, lo que permitió la construcción de 26 907 áreas potenciales. Sobre la base de estos resultados, se pueden realizar análisis intramunicipales para monitorear los indicadores de APS. Los parámetros modificables del algoritmo se pueden ajustar para adaptarse a diferentes conjuntos de reglas y a diferentes países. CONCLUSIONES: El uso de enfoques basados en geoprocesamiento puede crear condiciones para la evaluación del impacto de la APS conforme a bases de datos secundarias y a nivel intramunicipal, de la unidad básica de salud e incluso a nivel de equipo.

A comparative study of urban occupational structures: Brazil and United States / Estudo comparativo das estruturas ocupacionais urbanas: Brasil e Estados Unidos / Un estudio comparado de las estructuras ocupacionales urbanas: Brasil y Estados Unidos de Norteamérica

This paper compares the occupational structure of cities in Brazil and United States aiming to evaluate the extent to which the economic structure of these urban agglomerations is associated with the different stages of development, specifically when comparing a rich country with a developing one. Using a harmonized occupational database and microdata from the Brazilian 2010 Demographic Census and the U.S. American Community Survey (2008-2012), results show that Brazilian cities have a stronger connection between population size, both with occupational structure and human capital distribution, than the one found for cities in the United States. These findings suggest a stronger primacy of large cities in Brazil's urban network and a more unequal distribution of economic activity across cities when compared to USA, indicating a strong correlation between development and occupational structure.

Este artigo compara a estrutura ocupacional das cidades do Brasil e dos Estados Unidos, visando avaliar a extensão em que a estrutura econômica dessas aglomerações urbanas se associa aos diferentes estágios de desenvolvimento, especificamente quando se compara um país rico com um em desenvolvimento. Utilizando um banco de dados ocupacionais harmonizado e microdados do Censo Demográfico Brasileiro de 2010 e do US American Community Survey (2008-2012), os resultados mostram que as cidades brasileiras têm uma conexão mais forte do tamanho da população com a estrutura ocupacional e a distribuição de capital humano do que a observada em cidades nos Estados Unidos. Estes resultados sugerem uma primazia mais forte das grandes cidades na rede urbana do Brasil e uma distribuição mais desigual da atividade econômica entre as cidades quando comparadas aos EUA, indicando uma alta correlação entre desenvolvimento e estrutura ocupacional.

Este documento compara la estructura ocupacional de ciudades de Brasil y Estados Unidos de Norteamérica con el objetivo de evaluar la extensión a la cual la estructura económica de estas aglomeraciones urbanas se asocia en las diferentes etapas de desarrollo, específicamente cuando se compara un país rico con un país en desarrollo. Utilizando una base de datos ocupacional armonizada y microdatos del censo demográfico brasileño de 2010 y de la Encuesta de la Comunidad Estadounidense (2008-2012), los resultados muestran una conexión más fuerte en las ciudades brasileñas entre el tamaño de la población y la estructura ocupacional y la distribución del capital humano que la encontrada para ciudades de los Estados Unidos. Estos hallazgos sugieren una mayor primacía de las grandes ciudades en la red urbana de Brasil y una distribución más desigual de la actividad económica entre las ciudades en comparación con las de Estados Unidos, lo que indica una fuerte correlación entre el desarrollo y la estructura ocupacional.

Geolocation of hospitalizations registered on the Brazilian National Health System's Hospital Information System: a solution based on the R Statistical Software. / Geolocalização de internações cadastradas no Sistema de Informações Hospitalares do Sistema Único de Saúde: uma solução baseada no programa estatístico R.

OBJECTIVE: to describe a solution enabling geolocation of hospital admissions (AIH), processed on the Brazilian National Health System's Hospital Information System. METHODS: in order to spatialize AIHs an R language script was written, based on the microdatasus and CepR packages; the script was applied to identify all AIHs in Goiás state in the year 2015; after downloading and pre-processing the data, the procedure for AIH spatialization was detailed. RESULTS: of the 361,213 AIHs processed, we were able to retrieve 24,220 different ZIP codes (CEPs); from this set of ZIP codes, 23,910 (98.7%) were geolocated; these geolocated ZIP codes enabled spatialization of 97.7% of AIHs processed for the state of Goiás. CONCLUSION: it is possible to spatialize AIHs with a high success rate; the method detailed in this paper opens a new range of possibilities for the design of evaluation studies, formulation of policies and planning of health care actions.

Programa Mais Médicos: como avaliar o impacto de uma abordagem inovadora para superação de iniquidades em recursos humanos

[RESUMO]. Apesar de decorridos 40 anos da divulgação dos princípios de Alma-Ata, ainda persistem desafios para a consolidação da atenção primária à saúde (APS) como eixo norteador dos sistemas de saúde ao redor do globo. Dentre os desafios ainda presentes, merecem destaque as questões associadas à iniquidade na distribuição de recursos humanos em saúde. A experiência do Programa Mais Médicos (PMM) no Brasil é um exemplo de proposta voltada para a abordagem dessa agenda inconclusa de Alma-Ata. Ao modificar aspectos centrais da formação, provimento e alocação de profissionais médicos, o PMM mostrou-se uma saída viável para minimizar os desafios de escassez de profissionais. As avaliações do PMM, embora incipientes, produziram evidências positivas quanto a ampliação do acesso e melhoria da qualidade da APS no Brasil, um país de médio desenvolvimento econômico. Apesar disso, é premente a geração de evidências mais sólidas a respeito do impacto do PMM sobre indicadores de desempenho da APS. O debate apresentado ao longo deste trabalho discute a necessidade de se viabilizar estudos quase-experimentais capazes de mensurar o impacto do PMM junto à saúde da população. O artigo propõe, então, um conjunto de diretrizes que pode se configurar como um modelo aplicável para abordar desafios associados à escassez de profissionais em países de médio e baixo desenvolvimento econômico.

[ABSTRACT]. Despite the 40 years elapsed since the Alma-Ata principles were first launched, a series of challenges still persists for the consolidation of primary health care (PHC) as the backbone of health care systems around the world. Among these challenges, especially noteworthy are the issues associated with the inequality in the allocation of human resources. The experience of the More Doctors Program (Programa Mais Médicos, PMM) in Brazil is an example of initiatives that tackle this inconclusive Alma-Ata agenda. By changing key aspects of physician training, provision, and allocation, PMM was shown to be a feasible alternative to minimize the challenge of physician shortage. Assessments of PMM, even though preliminary, have produced positive evidence showing increase in access and improvement of PHC quality in Brazil, a middle income country. Nevertheless, the generation of more robust evidence regarding the impact of PMM on PHC performance indicators is urgent. The discussion proposed in the present article emphasizes the need to prioritize quasi-experimental studies to measure the impact of PMM on population health. The article thus introduces a set of guidelines that may become a useful model to approach challenges associated with the shortage of health care professionals in low and middle income countries.

Zika virus infection and microcephaly: Evidence regarding geospatial associations.

BACKGROUND: Although the Zika virus (ZIKV) epidemic ceased to be a public health emergency by the end of 2016, studies to improve knowledge about this emerging disease are still needed, especially those investigating a causal relationship between ZIKV in pregnant women and microcephaly in neonates. However, there are still many challenges in describing the relationship between ZIKV and microcephaly. The few studies focusing on the epidemiological profile of ZIKV and its changes over time are largely limited to systematic reviews of case reports and dispersal mapping of ZIKV spread over time without quantitative methods to analyze patterns and their covariates. Since Brazil has been at the epicenter of the ZIKV epidemic, this study examines the geospatial association between ZIKV and microcephaly in Brazil. METHODS: Our study is categorized as a retrospective, ecological study based on secondary databases. Data were obtained from January to December 2016, from the following data sources: Brazilian System for Epidemiological Surveillance, Disease Notification System, System for Specialized Management Support, and Brazilian Institute of Geography and Statistics. Data were aggregated by municipality. Incidence rates were estimated per 100,000 inhabitants. Analyses consisted of mapping the aggregated incidence rates of ZIKV and microcephaly, followed by a Getis-Ord-Gi spatial cluster analysis and a Bivariate Local Moran's I analysis. RESULTS: The incidence of ZIKV cases is changing the virus's spatial pattern, shifting from Brazil's Northeast region to the Midwest and North regions. The number of municipalities in clusters of microcephaly incidence is also shifting from the Northeast region to the Midwest and North, after a time lag is considered. Our findings suggest an increase in microcephaly incidence in the Midwest and North regions, associated with high levels of ZIKV infection months before. CONCLUSION: The greatest burden of microcephaly shifted from the Northeast to other Brazilian regions at the beginning of 2016. Brazil's Midwest region experienced an increase in microcephaly incidence associated with ZIKV incidence. This finding highlights an association between an increase in ZIKV infection with a rise in microcephaly cases after approximately three months.

Cadastro Nacional de Estabelecimentos de Saúde: evidências sobre a confiabilidade dos dados / National Registry of Health Facilities: data reliability evidence

Resumo O presente trabalho comparou a confiabilidade de um grupo de dados registrados junto às bases secundárias do Cadastro Nacional dos Estabelecimentos de Saúde. Para cumprir este objetivo, o trabalho foi realizado em 'survey' com 2.777 hospitais. Os hospitais visitados forneceram dados sobre equipamentos, localização geográfica, status de funcionamento e número de leitos. Quanto à concordância entre os hospitais visitados e o cadastro nacional, pode-se destacar que o status de funcionamento estava atualizado em 89% dos casos, o número de leitos em 44%, 82% mantinham o quantitativo de equipamentos correto e 63% apresentaram coordenadas geográficas precisas. Esses achados apontam para uma boa confiabilidade dos dados do Cadastro Nacional dos Estabelecimentos de Saúde, quanto às categorias comparadas, excetuando-se os dados referentes ao número de leitos cadastrados e quanto a existência de alguns equipamentos. Como desdobramento deste trabalho pesa a necessidade de discutir estratégias e incentivos para melhorar a confiabilidade dos dados que ainda apresentam inconsistências, de forma a ampliar a qualidade dos instrumentos utilizados para a formulação de políticas públicas.

Abstract This study compared the reliability of a data group registered in the secondary databases of the National Registry of Health Facilities. A survey was conducted in 2,777 with hospitals to achieve this objective. Visited hospitals provided information on equipment, geographic location, operating status and number of beds. Regarding matching data between visited hospitals and the National Registry, it can be noted that the operating status was updated in 89% of cases, the number of beds in 44%, 82% had the correct amount of equipment and 63% had accurate geographic coordinates. These findings point to a good reliability of information from the National Registry of Health Facilities, regarding the compared categories, excepting for data on the number of registered beds and for some equipment. As a further development of this work, we stress the need to discuss strategies and incentives to improve the reliability of data that still have inconsistencies, in order to improve the instruments used to formulate public policies.

Spatially balanced provision of health equipment: a cross-sectional study oriented to the identification of challenges to access promotion.

BACKGROUND: Access to health services is in part defined by the spatial distribution of healthcare equipment. To ensure equity in the provision of health services, it is important to examine availability across different health care providers taking into account population demand. Given the importance of the equitable provision of health equipment, we evaluate its spatial distribution in Brazil. METHODS: This study is classified as cross-sectional with an ecological design. We evaluate Brazilian data on distance to available health equipment considering: dialysis machines (385), magnetic resonance imaging (MRI) (257), hospital beds (3675) and bone densitometers (429). We define two distance thresholds (50 km and 200 km) from a municipality to the center of services provision. The balance between infrastructure capacity and potential demand was evaluated to identify a lack or surplus of health services. RESULTS: The distribution of dialysis equipment and bone densitometers is not balanced across Brazilian states, and unmet demand is high. With respect to MRIs, the large capacity of this equipment results in a large excess of supply. However, this characteristic alone cannot account for excesses of supply of over 700%, as is the case of the Federal District when the range is limited to 50 km. At the same time, four states in the Northeastern region of Brazil show a net excess of demand. Some regions do not meet the standard amount of supply defined by Brazilian Ministry of Health. The quantity and distribution of hospital beds are not sufficient to provide full coverage to the population. CONCLUSION: Our main focus was to evaluate the network of the provision of health equipment in Brazil, considering both private and public sectors conjointly. We take into account two main aspects of a spatially balanced health system: the regional availability of health equipment and the geographic distance between its demand and supply at the municipality level. Some regions do not meet the minimum requirement defined by the Brazilian Ministry of Health regarding the supply of health services.

Addressing geographic access barriers to emergency care services: a national ecologic study of hospitals in Brazil.

BACKGROUND: Unequal distribution of emergency care services is a critical barrier to be overcome to assure access to emergency and surgical care. Considering this context it was objective of the present work analyze geographic access barriers to emergency care services in Brazil. A secondary aim of the study is to define possible roles to be assumed by small hospitals in the Brazilian healthcare network to overcome geographic access challenges. METHODS: The present work can be classified as a cross-sectional ecological study. To carry out the present study, data of all 5843 Brazilian hospitals were categorized among high complexity centers and small hospitals. The geographical access barriers were identified through the use of two-step floating catchment area method. Once concluded the previous step an evaluation using the Getis-Ord-Gi method was performed to identify spatial clusters of municipalities with limited access to high complexity centers but well covered by well-equipped small hospitals. RESULTS: The analysis of accessibility index of high complexity centers highlighted large portions of the country with nearly zero hospital beds by inhabitant. In contrast, it was possible observe a group of 1595 municipalities with high accessibility to small hospitals, simultaneously with a low coverage of high complexity centers. Among the 1595 municipalities with good accessibility to small hospitals, 74% (1183) were covered by small hospitals with at least 60% of minimum emergency service requirements. The spatial clusters analysis aggregated 589 municipalities with high values related to minimum emergency service requirements. Small hospitals in these 589 cities could promote the equity in access to emergency services benefiting more than eight million people. CONCLUSIONS: There is a spatial disequilibrium within the country with prominent gaps in the health care network for emergency services. Taking this challenge into consideration, small hospitals could be a possible solution and foster equity in access to emergency and surgical care. However more investments in are necessary to improve small hospitals capabilities to fill this gap.
